Meghalaya's double-decker and single-decker root bridges are
unique in the world and are a sight to behold. The bridges are tangles
of massive thick roots, which have been intertwined to form a bridge
that can hold several people at a time. Khasi people have been trained
to grow these bridges across the raised banks of streams to form a solid
bridge, made from roots.

The living root bridges are made from the roots of
the Ficus elastica tree, which produces a series of secondary roots that
are perched atop huge boulders along the streams or the riverbanks to
form bridges.

The living root bridges, some of which are over a hundred feet long, take ten to
fifteen years to become fully functional, but they’re extraordinarily
strong – strong enough that some of them can support the weight of fifty
or more people at a time. The bridges are alive and still growing and gain strength over time.
